Aquatic ecosystems of the Arctic are very sensitive to the climate change. Thermic processes inside and around water objects (lakes, rivers, wetlands) affected by endo- and exogenous factors and lead to talik formation and geoprocesses interaction and turnover. Hydrological and geophysical investigation in the Lena River delta have been carried out in spring and summer 2016-2018. Sublake and subriver taliks georadar and electrical resistivity tomography data were obtained in a field with following hydrological and...

The northern polar region is under the influence of cold temperatures, increasing the effect of snow Arctic aquatic ecosystems affected by climate warming as well as human impact. Different scenarios of climate change show a possibility of temperature increase on 1-2?C and more depending of CO2 emission accounting. All global models give significant valuation to the Arctic exactly. Aquatic ecosystems take several parameters that allow to save their inner stable state and resilience. According to water physical par...
